Best practice to manage loss of loads and contact definition when remeshing

Bill_22179

Hi, since using HyperWorks, I became disapointed about the meshing/boundary conditions management. I was using Ansys in the past and it was way easier to manage the loads since the "collectors" where creating themselves. Also, I could change the load magnitude within the tree because the loads where defined by the geometry and not the FE entities (Nodes, element faces). Now using HyperWorks, I need to define the loads and create my "collectors" myself and the worst is if I remesh, I loose all loads definition, contacts, etc.. which makes it hard and time consuming to complete convegence study

 

What are your top tips and work arround to manage all of this? 

 

Thank you

Hey, Bill!

If you're using SURF based entities, such as pressures, contacts and so on, you can enable an option in File > Preferences > Mesh > Automatically update sets to mesh changes

Examples. Note how many elements there are in the set:

Pressure before remeshing

After remeshing

It also works for SPCs:

If I may, I'd suggest using Altair SimLab. It offers a workflow more similar to what you're used to, and it's got a great Learning Center, with loads of video tutorials. Check it out: https://web.altair.com/altair-for-simlab-learning-center-trls

Thank you, it will help for sure. 

However, I'm still interested to see that method people use to simply the convergence testing with hyperworks. In the case you mentionned it will work great, however this won't work with forces applied on rbes or spcs on rbes?

 

Do you manually reapply all loads and constraints?
